Are you uninstalling R03 before uninstalling PS4.0? What are you trying to accomplish by uninstalling Citrix? Typically the PS servers that I build are expendable so I can simply reimage or rebuild a server (scripts) quickly. I've been burned too many times by Citrix's installers.

Our servers are Win2k3 SP1, PS 4.0 with R.03 applied. If I initiate an uninstall of Citrix, the uninstall will run through with no problems but on system restart the server will boot right up to blue screens. Safe mode will boot up, but I've been unable to track down the BSOD culprit from there. (almost all citrix services are not listed in the registry or services) My only work around has been to boot up to "last known good configuration" at which point Citrix is still 'uninstalled' from the file system but all citrix services show up in the services list. At this point I can manually wipe all of the calls to citrix services from the registry, and start a clean Citrix installation. I've had the problem with uninstalling Citrix prior to the update to R.03, and can easily reproduce it on new system installations (not working off of preset server images). More annoying than anything, as I don't need to do uninstalls much; but I'd love to know a quicker resolution to this if someone has one :). thanks, Lan
